Title: Improvements in and relating to devices for raising and lowering spare wheels of vehicles
IPC: B62D43/00
Filed: 1958-12-10
Abstract: 844,992. Spare wheel carriers. TATRA NARODNI PODNIK; Dec. 10, 1958 [Jan. 27, 1958], No. 39897/58. Class 136(1). A device for raising and lowering the spare wheel of a vehicle comprises a supporting arm 1 having one end pivotally mounted in a bearing member 3 and the other end arranged to receive a vehicle spare wheel 6, a catch 24 being, provided to co-operate with a securing lever 9 when the supporting arm 1 is in the raised position, and a pneumatic cylinder 14 and piston 17, the piston 17 being connected by a rocker arm 18 to a pull rod 16 and the rod 16 being connected to a toggle linkage 20, 22 one end of which is pivoted at 21 to the arm 1, the arrangement being such that movement of the piston 17 operates the toggle linkage 20, 22 to raise or lower the supporting arm 1. As shown in Fig. 2, two oppositely directed wheel supporting arms 1, 15 are provided and the toggle linkage 20, 22 is pivoted at each end to one of the supporting arms. The wheels 6, 10 are supported on tiltable members 5 each carrying two longitudinally extending arms 8 between which is pivoted a suspension arm 31 carrying the catch 9. The locking position of each arm 1, 15 when not loaded with spare wheels, is secured by a strut 25 pivoted at one end to a bearing 26 and secured at its other end by a hook 29 To lower one of the spare wheels the appropriate securing lever 9 is released and the lever 12 of an overflow air valve 13 is partly turned, compressed air is thus caused to escape from the air cylinder 14 and, at the same time the air inlet from an air reservoir (not shown) is closed. The arm 1 or 15 and its' spare wheel 6 or 10 are thus free to drop under their own weight pulling the rod 16 down, the piston 17 being pushed up through the medium of the rocker arm 18. To raise the spare wheels the outlet of compressed air from the air cylinder 14 is closed by means of the lever 12 and compressed air from the reservoir is admitted into the cylinder 14. This pushes the piston 17 down and the pull rod 16 moves up through the medium of the rocker arm 18, whereby either strut 20 or 22 abuts against a firm pin 21 and the other strut which is stationary pushes the arm 15 or 1 up together with the spare wheel 10 or 6 to its upper position where it is locked by means of the lever 9.

Title: Treatment of metallurgical slags for the production of a coagulent for clarifying water
Inventor: IONESCU TUDOR
IPC: C02F1/52
Filed: 1959-11-26
Abstract: A coagulent for clarifying drinking, industrial and waste waters is obtained by treating a previously crushed or ground slag obtained in the extraction of copper or lead with a dilute aqueous mineral acid, filtering off any undissolved residue to leave a solution containing silica in colloidal suspension and dissolved metals.  The acid may be dilute hydrochloric or sulphuric, or sulphur dioxide or carbon dioxide may be passed into an aqueous suspension of the slag.  If the slag is completely dissolved any excess silica over 1 g. per 100 ml. solution may be removed and copper may then be displaced by iron, preferably to give an iron content of at least 2.5 g. per 100 ml. The liquid product may be mixed with more untreated slag to give a pasty product which is also useful as a coagulant.

Patent GB-1375085-A (GB)
IPC: H01H43/10
Filed: 1972-09-01
Abstract: 1375085 Time switches DIEHL 1 Sept 1972 [2 Oct 1971] 40540/72 Heading H1N A time switch having a synchronous motor drive and means for manually setting a switching time interval is provided with blocking means which can be actuated by control means to hold fast part of differential gearing between the motor and setting means, thereby initiating a timing period and simultaneously preventing manual operation of the setting means. As shown a motor 21 rotates planet pinions 13 and 14 meshing respectively with sun gears 11 and 15 loosely mounted on shaft 4. Gear 15 is integral with a castellated locking disc 16 which can be held fast if a control means 20 lifts rod 30 to allow spring 31 to insert a lever 18 into a notch 17. A shaft 3 having a setting knob 7 is coupled to gear 11 by gear 8 and carries a cam disc 10 controlling contacts 24, 25. There is normally no coupling between shaft 3 and motor 21, but when disc 16 is locked the reduction due to gears 8 and 11 and differing numbers of teeth on wheels 11 and 15 and also on pinions 13 and 14 substantially prevents manual rotation of knob 7. Prior to such locking the knob 7 may be turned to preselect a desired time interval, subject to a limit set by a lug 32 on cam 10 engaging a fixed stop 33. This action closes contacts 24, 25 to energize motor 21 which runs freely until control means 20 is actuated, whereupon a time drive to shaft 3 is established and cam 10 is restored until a nose 27 on contact blade 26 enters a recess 28 to open contacts 24, 25 with a snap action (due to lost motion of a drive pin 9 in sector-shaped recesses 29). This de-energizes the motor 21 but the device cannot be again switched on or reset until control 20 has unlocked disc 16. The control 20 may be a pressure or temperature sensor.

The passages may lie at different radii R, may converge or diverge, and may be of spiral form. the rotor may comprise a cylindrical sleeve with straight or curved blades (1a, 1b), Figs.1 to 4 (not shown) radiating therefrom. The tips of these blades may be radially spaced from the grooved portion of the housing, or they may be provided with teeth which cooperate with the concentric grooves 5. The blades may have holes or slots (32) therethrough of the same or of different cross-section, and in the extreme case the blades may be in the form of screens or grids. The blades (1a, 1b) may extend axially across the full width of outlet 10, or across only a part thereof, Fig. 1 (not shown).
